Aaron Carter, the still young and grown-up singer, popped the question Sunday night September 17th to girlfriend, Playboy Playmate Kari Ann Peniche.
Aaron, 18 popped the question to Peniche, 22, who previously dated brother Nick Carter, in Las Vegas while they were onstage in front of 200 people during the Playboy Comedy Tour at the Palms Casino Resort.
"I'm very excited about it," Peniche tells People about the surprise proposal. "I don't remember it happening. It was such a blur. I had no idea he was going to do this, but I'm glad he did."
Both Aaron and Peniche reportedly are planning to get married in the next six months.
